NVidia Nsight Debugger - Geometry window doesn't work

I programmed an application that displays a quad, which works perfectly. However, if I try to debug my application with NVidia's Nsight debugger, the quad is not shown in the Geometry window. Even if I switch to the memory tab, the submitted vertices in the vertex and index buffers are not visible. The strange thing though is, that if I watch the buffers in the resource window, they are shown correctly.

This is a image of the application when it is running: Running application

This is an image of the resource view (vertex buffer and index buffer): Vertex Buffer resource view Index Buffer resource view

Here are the geometry window tabs: Geometry memory window Geometry graphical view

I am using DirectX 11 with Visual Studio 2015, if that's important.

Solution

  • I found the reason for NSight to fail to display the geometry...

    On initialization of the Input Assembler (IA) stage I used the D3D11_APPEND_ALIGNED_ELEMENT macro when initializing the D3D11_INPUT_ELEMENT_DESC structure. If I set those values manually, NSight displays the geometry correctly.

    I still don't know why that's the case. Is it intended by NVidia or is it just a bug?
